No.

How did you come across this need?
Sounds like an app design flaw.
What is the original problem you're solving?

P.S. It may be possible in specific cases when you know (from code)
how mempool sets buf_addr for a given mbuf,
and that PMDs don't change buf_addr with the used set of offloads.
Apparently, this approach would be extremely brittle and dangerous.
